Stevenson Motorsports has announced it will cease racing operations following the IMSA season-ending Petit Le Mans at Road America on Oct. 7.

"After 15 years of racing professionally, the difficult decision to remove ourselves from motorsports competition is nothing less than heartfelt," said team owner Johnny Stevenson. "We regret to inform you all that we are ceasing racing operations following the close of the 2017 season in all classes and series. But, we find it is time to move on. We thank you for all your friendships, respect, help, and of course the successful competition you all have provided throughout those years. We will miss you all at the track. Hopefully we can finish on a real high note at Road Atlanta."

The North Carolina-based team has competed in both the IMSA WeatherTech SportsCar Championship and IMSA Continental Tire SportsCar Challenge with a variety of different manufacturer platforms.

Since debuting in the IMSA ranks in 2003, Stevenson Motorsports has made over 270 race starts with 25 pole positions, 33 victories, and 75 podium results. The squad claimed the North American Endurance Cup Championship title in 2013 and won the 2015 IMSA Continental Tire SportsCar Challenge championship.

The team has campaigned the No. 57 Audi R8 LMS in WeatherTech competition and the No. 57 Camaro GT4.R in the CTSCC this year. Audi drivers Andrew Davis and Lawson Aschenbach drove to victory earlier this season at Canadian Tire Motorsport Park.

Stevenson Motorsports Camaro GT4.R drivers Robin Liddell and Matt Bell took two victories at Canadian Tire Motorsport Park and Lime Rock Park. The pair finished runner-up in last weekend's event at Virginia International Raceway.
